i was thinking about making a new intake for my 86 n/a, it would be made out of 3" alum pipe with a fabricated peice for the part where it mounts to the tb

BUT!!!!!
is there such a thing as a universal mass airflow sensor, cause i would take the "little box from hell" and replace it producing greater amounts of air into the intake.......

is this good idea???

This is a good idea, but unfortunately it's not possible. The AFM's output is specific to the ECU, so there's no such thing as a universal one. You can remove it entirely by going to aftermarket programmable EFI.
The intake pipe's a good idea too, and quite possible!

i read somewhere that you can buy an aftermarket maf that just uses two wires or something, i can't really remember. I do remember it was expensive though.

You need a lot more than two wires for a MAF sensor...

hyperdaddy7

if i remember right it worked liked this- one wire is in front of another wire inside the maf. one is infront of the other. the front wire heats up and is at a certain temp. the second wire is basically a thermometer and it measures the air that passes the first wire. As more air flows through, the temp is going to get lower, becasue the air passes by at a faster rate and vise versa.

like i said i am not really sure on this...You know a lot more about this stuff than i do.

Aah, that's a hot-wire air flow meter (it's a little more complicated than your description but you've got the basics). Totally different beast to the trapdoor AFM's we have, and would be even harder to retrofit! This is a true "mass air flow" meter' the trapdoor types actually measure volume flow, then the ECU converts it to mass flow using a temp sensor built into the AFM, hence the extra wires I was talking about. You did say "MAF", I shoulda picked that up!
